Philadelphia's Lost Waterfront
We're now walking over Delaware Avenue—or Columbus Boulevard as it's now called. It was first an irregular footpath next to the river, built over docks and piers that had outlived their usefulness. Over time, though, it became a more formal thoroughfare, thanks to Stephen Girard. He specified in his will that a wide boulevard should be constructed along the Delaware River.
The project took place between 1834 and 1845, with improvements continuing until 1900. This bumpy street became the widest and longest riverside avenue in the world.
Keep going now, to the end of the viaduct.
